Timer quits shutting the lights off and time flashes 12:00AM

Our timer is a model EJ500 about 1 year old. In the last week it has quit shutting the lights off twice and the time starts flashing 12:00 AM. All I have to do is reset the current time and it starts working again. Any suggestions?

Intermatic is a reliable mfg. if you have a it wired to directly to a light and only a light, you most likely have a defective timer. Bring it back and purchase a rotary timer with on-off switch. more reliable. I too installed the same type of timer and went through 3 before installing intermatics rotary timer/switch.

I have an Intermatic PF 1102T that is about 15 years old. The timer (clock) has quit keeping time. It will come on if you manually turn it on. You have to manually turn it off as well. How difficult is it...


1) Copy following link for timer module model numbers and wiring:
PF1100 series appears to use PB913N84 timer module.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#PB

2) Timer module for PF1100 series is held in place using phillips-head screws.
It should be easy to replace, although I have not fixed this specific product. You may need new terminal connections from hardware if existing timer module is hardwired.

How to open to repair Woods 24 Hour Digital Outdoor Timer with Photocell Mfr # 13660


1) Copy following link to identify timer, and select replacement if needed.
http://waterheatertimer.org/Woods-timers-and-manuals.html#2001

2) There is no reset button on this type of timer.
Nor is there a repair manual for $16 timers.
Generally people buy another timer since the timing chips and parts are delicate, easily damaged by power surge, and often quit working before 1 year warranty expires, and usually last a few years before no longer functioning. The photoeye sensor is often a failure point.

3) Check outlet for 80% rated voltage.
Check timer on different outlet.
Use circuit analyzer and test outlet for correct polarity and grounding.
Test and replace GFCI outlets as needed.

I replaced an old Malibu 300 watt powerpack with a new digital 300 watt Malibu power pack and when I turn it on it runs for about a miniut and then shuts down. I have 15 11watt light on it, the same as the...


300 watt power pack should have 300 watt load.
You have 165 watt load.
Copy following link for general tips to get Malibu power pack to last longer.
http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

Problem might be the photo eye.
http://waterheatertimer.org/images/Malibu-8100-9045-01-large.jpg
Rotate manual dial to ON position and see if lights turn ON.
Keep in mind the digital power pack has photoeye that is light sensitive, and must be exposed to dark light to activate.
For timed functions. Rotate manual dial until it points at timer. Press clock set function button, and use up-down buttons to set current time. Press timer ON button, and then use up-down to set ON timer. Then press timer OFF button , and use arrow keys to set OFF time.

This product has 1 year limited warranty, contrast with old-type analog power pack with 5-year warranty.
Malibu does not even post a manual on their site, which might have troubleshoot section to illuminate why your system has problem,

Just installed a in-wall digital timer model 59018 and when we try to program it when we hit the clock button the unit shuts off so we are unable to set the time (or anything)


Woods 59018 single-pole 7-day 7-program timer, color white:
http://waterheatertimer.org/Woods-timers-and-manuals.html#59028

I test timers and 3-5% arrive defective, and they never work. Some stop working within 1 year, and some last quite a while.
Timers are affected by line interference and polarity issues. So wiring in home has to be correct before timer will operate as expected.
Timer has to be installed correctly with each wire correctly connected.
Press manual override button and see if lights turn on-off. This will indicate if your timer is wired correctly. If lights do not turn on-off with manual override, the open link above for wiring instructions.
To begin programming, reset timer by pushing in the round reset button with toothpick or paper clip.
12:00 am Mon should display.
If the above items are all correct, then defective timer is suspect.
If you try multiple timers, and each timer has same problem, then line interference or bad wiring is suspect, or you are buying from somebody who has a bad batch of timers.
Try wiring same timer at neighbor's house and see if it works there.

When I hook up the unit and put it to timer the lights go on and off continuously in rapid fir order. What is wrong


Sounds like the timer is defective.

For some reason, GE15004 is always on fixya.
People can't figure out how to set it.
The manual is unclear and incomplete.
Yours is first complaint of timer malfunctioning
http://waterheatertimer.org/GE-timers-and-manuals.html#15004
I test timers. 4-6% arrive defective. Most last a few years. Some last quite a while.

Our Intermatic EI200W is 1 1/2 years old and it has stopped working the way it should. It turns on the fan unit, it runs for 5 seconds and shuts off, it can be re turned on but again it only lasts for 5...


The problem could be the Load and not the timer.

I discovered that if there is a problem on the circuit, that these electronic timers can malfunction.
Buy circuit analyzer from home center, test nearby receptacle that is on same circuit.
If there is a ground fault, for example in your light-fan-motor, you have to track this down with multimeter or some other testing device.

If the circuit is clean, and your electronic device has malfunctioned, then bad news: There are no repairs for in-wall electronic devices.

I test timers: 4-6% arrive defective. Many go bad first year or two. Some last quite a while.
Some programmable timers can be reset and the timer recovers.

Intermatic page below shows countdown timers.
http://www.intermatic.com/products/timers/in-wall%20timers/electronic%20auto-off%20timers.aspx
Sample manual shows 1 year limited warranty for your product:
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/ei200%20-%20english.ashx

If I can make a replacement suggestion:
Manual spring-wound countdown timer lasts for 10 years because it has no electronic parts.
I have three of these and they work without a problem even on circuits that have small ground faults.

My GE Smart Digital timer won't shut off at the assigned time, but it will shut down manually.


I am guessing that you have digital in-wall timer GE 15071 or GE 15086

To identify timer for sure, see images at following link:
http://waterheatertimer.org/GE-timers-and-manuals.html#15071

Manual for 15086
http://waterheatertimer.org/pdf/GE-15086-Manual.pdf

If this is new timer, the problem could be a couple things.
1) Circuit has electrical problem that is affecting timer electronics.
Use circuit analyzer from Home Depot electric department and test any receptacle on same circuit breaker as timer.
2) event1 ON was programmed but event1 OFF was not programmed. To review events, press Prog button once to see event1 ON and press Prog button again to see event1 OFF. When review is complete, press clock key to return to current time.
3) event1 ON and event1 OFF are programmed with conflicting day schedules
4) event1 and event7 have conflicting schedules

If this is new or old timer:
5) Timer needs to be reset because of internal glitch. Press and hold reset button for a moment and timer display will start flashing 12:00 am MO
6) These timers can go bad any time. I test timers and 4-6% arrive defective, and most quit after couple years, but some can last quite a while. This is why I suggest using a circuit analyzer to check if circuit is causing difficulties.

I can not get the timer to come on at the correct time. The dark colors are PM and the White background is white. But AM is from 6:30 to 6:30. I want the lights to come on at 4:30 to 10PM. I have tried...


Your timer could be broken.

But let's review.
Override set atTimer on > correct
When override is moved other direction, then lamp turns on.
Lamp fixture is turned on
Bulb is good
Receptacle has power
You tied timer on different lamp at a different receptacle.
Dial rotates with passing time, which indicates that clock motor is functioning
Dial does not get stuck during rotation, and makes complete 24 hour circuit in 24 hours, indicating that clock motor is not weak.

Segments up or down for timer functions >> here's what to do: pull up some segments. Manually rotate timer dial clockwise.
The lights will turn on-off as you rotate dial manually.
That will confirm if up or down is correct position of segments.

If everything above checks out, timer should work.
If timer is defective, exchange for another one.

I test these timers and 4-6% arrive defective. Most last one or two seasons and then they quit.
Some last years.
But timers today are priced low enough.
